Meet our sheep

From our 3rd floor bedroom

So the story goes like this.....Once upon a time, our landlord (Peter) says to our neighbors, "By the way, you have to mow the grass in the back" Keeping in mind that it's like 5 acres of tall grass back there, they say, "I don't think so. Why don't you hire someone and I'll give you some money". We'll next thing you know these alleged sheep show up, 5 of them in our backyard. Our neighbor, Ed, looks at them, observes the prominate horns, and tells Peter that he bought goats not sheep. After some debate and consulatation of Mr. Google, we think that they may actually be some exotic form of sheep. Confirmation would be appreciated. I'll try and get some better close ups in the near future.
